CI on GitHub via `haskell-ci github happy.cabal`

andreasabel commented 3 years ago

Out-of-the box CI on GitHub using the haskell-ci tool, put patched for happy, similar to https://github.com/simonmar/alex/pull/189.

DEVELOPER.md explains how to regenerate the CI, e.g. in case of new GHCs.
.github/haskell-ci.patch modifies the generated workflow by:
- Setting flag 'bootstrap' to False in calls to cabal.
- Installing happy instead of just building it.
- Setting HAPPY and HC for running the tests.
tests/Makefile has been modified to not overwrite already set HAPPY and HC variables. This is needed to locate these executables correctly.
cabal.haskell-ci contains configuration for running haskell-ci: It removes constraints on packages containers, mtl and transformers. Otherwise, these will be constrained to the GHC-shipped versions, which isn't compatible with happy for all GHC versions.

[fixes #189] [fixes #193]

Can you delete Travis too?

I emailed @simonmar and @int-index about enabling GitHub actions in this repo.

Avec plaisir. Voila!

Good. I do not fully understand how this works, but it could be that the actions run as soon as they are in master...

Oh right, that might be how it was before. Well, taking the risk :).
